BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a motor stator, particularly to one able to quickly complete winding work, economizing resistance enameled wires and enabling resistance enameled coils to be arranged safely and evenly.

2. Description of the Prior Art

A conventional inward turning motor stator is to have a silicon steel seat bored with a plurality of coil holes respectively inserted therein with an insulating thimble and then plural resistance enameled coils are respectively inserted through the insulating thimbles and wound on the silicon steel seat. After the resistance enameled coils are wound on the silicon steel seat, each set of coil has to be trimmed and bunched by means of cotton yarn. The coils of the conventional motor stator can hardly be wound evenly and smoothly and hence they have to be pressed flat and fixed in shape. Therefore, the whole winding and wire trimming work becomes extremely complicated, and in the course of pressing and shaping, the coils are likely to be damaged to affect their exciting effect. Apparently, it requires lots of time and trouble to make the conventional motor stator, and the exciting field of the conventional motor stator is comparatively small, thus consuming a great quantity of electricity.
